Final answer:
The correct answer is B. Propranolol. CD24 is a non-selective beta-blocker with low extraction ratio, long half-life, and intrinsic sympathomimetic activity (ISA).
Step-by-step explanation:
The correct answer is B. Propranolol.
CD24 is a non-selective beta-blocker with low extraction ratio, long half-life, and intrinsic sympathomimetic activity (ISA). Propranolol is a non-selective beta-blocker that fits this description. It is commonly used to treat cardiovascular diseases by blocking the beta-receptors associated with vasoconstriction and cardioacceleration, thereby improving cardiac function.
Other options such as atenolol, metoprolol, and labetalol are selective beta-blockers and do not possess the same properties as CD24.
Propranolol is a non-selective beta-blocker that has a low extraction ratio and long half-life. It is commonly used to treat cardiovascular diseases by blocking beta-adrenergic receptors which helps in reducing vasoconstriction and cardiovascular stress.
